<div class="textblock"><p>This file consists of a self test example which uses the <a class="el" href="struct_x_ipi_psu.html" title="The XIpiPsu driver instance data. ">XIpiPsu</a> driver to send an IPI message to self and get a response Each IPI channel can trigger an interrupt to itself and can exchange messages through the message buffer. </p>
<p>This feature is used here to exercise the driver APIs. Example control flow:</p><ul>
<li>Init the IPI and GIC drivers</li>
<li>Setup Interrupt System with IPI handler which inverts the received message and sends back as response</li>
<li>Write a Message and Trigger IPI to Self.</li>
<li>Keep polling for response till timeout</li>
<li>Interrupt handler receives IPI and sends back response</li>
<li>Read the received response and do a sanity check</li>
<li>Print PASS or FAIL based on sanity check of response message</li>
</ul>

2.2  ms  01/23/17 Modified xil_printf statement in main function to
                  ensure that "Successfully ran" and "Failed" strings
                  are available in all examples. This is a fix for
                  CR-965028.
